[Arrhythmias in healthy sailors].
Results are presented of 24-hour monitoring by Holter's method of ECG in 50 healthy seamen aged 29-55 years (mean 47.7 years), in whom clinical examination, chest radiography, resting ECG records, and echocardiography confirmed normal condition of the cardiovascular system. In 36% of the seamen premature beats of various origin were elicited. Supraventricular extrasystolic beats were demonstrated in 8%, atrioventricular-junction beats in 8%, and ventricular ectopic beats in 18%. In one case simultaneous occurrence of junction beats and ventricular beats was found. In 28% of the subjects sinus bradycardia was noted, and in 1 seaman two episodes of sinus tachycardia were recorded. The intensity of the observed arrhythmias was low.
